Anodising of aluminium and its alloys in conventional anodizing electrolytes such as sulphuric, oxalic, chromic and phosphoric acid to get the required physical properties for desired applications are well known. Anodising in organic acids was also investigated in the past. Hard anodizing at ambient temperature to get thick, hard and wear resistance coating on aluminium alloys using sulphamic acid which is one such promising electrolyte. This electrolyte system has been selected due to lesser agrassive power and ability to produce more compact oxide film on aluminium alloys. So a systematic investigation has been carried out and the physical properties of the oxide film produced under various operations conditions are measured. The effect of concentration, temperature, current density and addition agents on the quality of the oxide film are reported and the results are discussed
